| 13 | <para>All programs compiled in <xref linkend="chapter-cross-tools"/> will
|
|---|
| 14 | be installed under <filename class="directory">$HOME/cross-tools</filename>
|
|---|
| 15 | to keep them separate from the host programs. The programs compiled here are
|
|---|
| 16 | cross tools and will not be a part of the final LFS system. By keeping these
|
|---|
| 17 | programs in a separate directory, they can easily be discarded later after
|

| 18 | their use.</para>

| 20 | <para>Create the required directory by running the following as

| 21 | the <systemitem class="username">lfs</systemitem> user:</para>

| 25 | <para>The next step is to create a <filename
|
|---|
| 26 | class="symlink">/cross-tools</filename> symlink on the host system.
|
|---|
| 27 | This will point to the newly-created directory in your home directory.
|
|---|
| 28 | Since normal users will not have permissions to write to the root tree,
|
|---|
| 29 | we need to exit the <command>su</command> and run the symlink command as
|
|---|
| 30 | <systemitem class="username">root</systemitem>:</para>

| 34 | ln -s $LFSHOME/cross-tools /

| 38 | <para>TO BE REWRITTEN - The created symlink enables the toolchain to be
|
|---|
| 39 | compiled so that
|
|---|
| 40 | it always refers to <filename class="directory">/cross-tools</filename>,
|
|---|
| 41 | meaning that the compiler, assembler, and linker will work both in
|
|---|
| 42 | this chapter and this host architecture and in the next (when we are
|
|---|
| 43 | <quote>chrooted</quote> to the LFS partition).</para>
